Why is Thomas A. Edison called the father of motion pictures?

The early movie projector showed the film onto a screen, so that a roomful of people could watch at the same time. Edison bought the rights to this machine and started making his own projectors. That is why he is sometimes called the "Father of Motion Pictures."
